i To all whom it may concern:

- Be it known that I, MORTIMER C. Rosina. new, a citizen of theUnited States, residing at Cleveland, in the county of Cuyahogaand Stateof ()hio, have invented a certain new and useful Improvement in I nsulator-Supports, of which the following is a. full, clear, and exact description, reference being bad to the accompanying drawings. P

This invention relates to. insulator posts,

such as are employed for the purpose ofsup-.

porting, through an interposed porcelain or glass insulator, a cable or heavy conductor wiref These posts are, asaqndinarily constructed, fastened rigidlyto a, cross arm or other supporting base. In us'efjit frequently happens that the cable or heavy Jconductor or feed wire is not efficiently supported by the insulator, as by failing to rest properly upon and register accurately with the groove, provided therefor in the insulator proper. v

It is the principal object of this invention to" provide a construction of post where by the 0st and insulator may be very convenientfy adjusted to overcome the objections noted and without the necessity for removing the post from itssupport. 1

I accomplish the foregoing results 'by the construction illustrated "in the drawings forming part hereof. wherein- Figure 1 represents a "iew, tion and partly in elevation, o post constructed in' accordance with my invention. showing the mannerof its application to its support; Fig. 2 represents a sec tional view corresponding to the lines 22 partly in secsaidpost.

Describing the various parts illustrated herein by reference characters, 1 denotes the supporting base for the post, which base maybe a cross-arm or any other supporting Specification of Letters Patent. I Application filed January c, 191;.- Serial No. 140,323.

an insulator.

i denotes an insulator which is cemented j onto-the bushing 5 and is provided with a Y downwardly extending skirt 8 which surrounds the upper end of thepost and protects the same from the weather.

The insulator shown herein may be of glass, porcelain, or other suitable insulatmg'matcrial, and is shown as having a concaved seat9 in its upper surface with later-' ally projecting wings 10 on opposite sides of said seat. said wlngs providing convenlent means for securlnga cable or conductor 11 in place on to of the insulator and-in'the seat t ereon. he cable or conductor. may be secured to the wings, as by means of a wirelQ.

Cooperating with the flange 3is a clam said clamp consisting of'a member "which is adapted to be inserted into the post and to engage the flange 3 and means for securing this member to the supporti g base. The I member which is insertedw ithinthe base is designated by the numeral 13 and is preferably a block of metal which is generally oblong in shape. and of such'lengthas to extend diametrically across the opening It in.

the bottom of the post 2 andhaving lateral ledges 15 adapted to engage, the annular flange 3. Beneath these ledges the block'is rounded, as shown at 16, the surfaces 16 be'- ihg cylindrical and the diameter of the cylindrical portion of the block being sufficiently less than the internal. diameter of the flange 3 to proxide clearance and at the-same time prevent the disengagement I of the ledges-15 from such flange whentheblock is in place. The block 13 lS.-Sl10\\'ll "as provided with a pair of threaded apertures which are adapted to receive the threaded ends of a pair of bolts 17:. said'bolts being shown as extending through =thesupport 1 and having heads 18 adapted to .engage'ther bottom of such support. 4- l By making the bolts; 1.? considerably longer than necessary to extend-through the support 1 and the block '13.;one of these bolts may be shoved through the aperture provided in the'support and threaded into the bottom of one of the holes in the block. with the block considerably elevated above the support. The post can then be applied to the block by tilting it at such an angle as to enable the block to enter the hole ll. The post can then be straightenei'l up and the other bolt insertedth ough the support 1-,

andthreaded into the bottom of the other oieili' the lblo clc "13. Both b'o-lt's' ma then beset up and the block'be drawn down to its seat, as shown in Fig. 1.. Should it be necessary or desirable to adjust the post 2 axially, it will benecessary only to unscrew .the blts 18 a short distance andv'rotatethe post the desired extent. Then-by setting up on the bolts 18, the post may be clamped firmly in its new position.

I" By using slotted support 1, one of thebolts may' bef connected'to the block 13 and 1 place. I I

By the construction described and illusthe block then inserted into the post'and the assembly may be applied to theusupportingv base by insertingthis bolt into one of the "slots. The other bolt may, thenbe inserted into the support, -threaded into the block, g ing the'rewithin an inwardly projecting an-' and both bolt'sset up, clamping the post in trated herein, it will be apparent that I have "produced an insulating post that may be ad- 3 1 Th ombina tiom with a hollow insulaju sted to adapt itand the insulator secured thereto to varying conditions of use and,-

Having thus described my invention, what I v I claim is tor post having an annular inwardly projecting flange in the interior thereof, ofa a support for said post, a block within said post and adapted to extend across the space clamprthe block to the flange andthereby se-.

within and to engage opposite sides of said flange, said block being of such shape as topermit it to be inserted into the post through the space bounded bysaid flange, and adjustable means extending through said'support and engaging said block and serving to cure the post to the support.

2. The combination of a hollow post having an inwardly projectingannular flange at its lower end, a clamping member within the post and adapted to engage said flange, said memberbeing rotatable relative to said post, a support for said post, and means engaging the clamping member and securing.

rotation of said clamping member.

3. The combination? of a post having an internal annular flange near its lower end,

. said post being rotatable relative to said I a support for said post, and means within said post and engaging the flangeand adjustably securing the post to the support,

means and said .means'being non-rotatable,

relative to said support. g

. 4. The, combination" ofa'hollow' post having therewithin aninwardlyprojecting annular; flange near its bottom, a clamping and engage the same, said post and clampmember within said post andhaving a ledge or projection adapted to overhang the flange v ing member being relativelyrotatable, a]

support'for the post, andsecuring devices 5. The combination .of a hollow post hav nular flange, a clamping member within said post adapted to overhang the flange and engage the same, saidclamping member 3 having a plurality. of threaded apertures I therein, a support forthe post, and a plurality' of bolts extending through the bottom ofthe'post and threaded into saidapertures j to secure the post to the said support.

6. The combination of a hollow post having at its bottom an inwardly projecting annular flange, a support for said post, a

clamping member within the post comprising an oblong block -of less Width than the internal diameter of the flange and of greater length than such diameter of the I flange whereby it..is adapted to overhang and engagethe upper surface of the flange,

said support and a bolt extending through and threadedinto said block;

7. The-combination of a hollow post hav ing therewithin an inwardly projecting annular flange, a support for said post, a block within said post, said block being of less width than the internal diameter of'the flange and being of greater length than such internal diameter of the flange whereby ledges are provided for engaging the opposed portions of the upper surface of the flange, said block being provided below such ledges'with cylindrical surfaces adapted to center the block with respect to said flange, and a bolt extending through the support and threaded into said block.
